senior cat ignoring clean box for the rug

My ten-year-old tabby used to be the most reliable cat in the world, but recently she keeps peeing on the bathroom rug right next to the box. I cleaned the box twice this week and switched to unscented clay, but it is still happening.

I am not sure if this is a behavioral issue or if she is having trouble getting in. She seems to hesitate before stepping into the box, but she does not cry out. I have started keeping a log of the times it happens to look for patterns, but so far it is mostly in the evenings.

The hesitation is a significant data point. At ten, joint stiffness is a primary suspect. If the entry is too high, the effort required to jump in may exceed the comfort threshold.

I would check the height of the box. If it is standard, try lowering it or using a tray. Also, review the placement. If the box is near the food, some cats avoid it. See box placement: near the water or far? for spacing guidelines. The rug texture might also be preferred over the clay for some reason, but the physical barrier is the most likely cause for a senior cat.

I agree with the focus on physical access, but we must rule out medical causes first. In my experience, changes in elimination habits are often the first sign of urinary tract issues, even if the cat does not seem in pain.

I would recommend the following:
- Schedule a vet visit for a urinalysis.
- Monitor for any blood in the urine.
- Check if she is drinking more than usual.

If the vet finds nothing, then we can move to behavioral solutions. Please do not ignore this step, as untreated infections can become severe quickly.

Mary is right to prioritize the medical check. However, if the vet clears her, look at the texture preference. Some senior cats with arthritis find the granular feel of clay uncomfortable on sore paws.

I switched my gray shorthair to a softer, larger pellet litter when she became picky. It made a difference. Also, consider that the rug might be more absorbent and forgiving than the hard floor. If the medical workup is negative, I would try a different litter texture before changing the box location.

It is important to be gentle with your cat during this transition. Punishing the behavior will only increase her stress and likely make the soiling worse. She is not trying to be difficult; she is dealing with a change in her body or environment.

I have seen many senior cats benefit from a low-entry box. It reduces the impact on their joints. You can find some good options in best low-entry boxes for seniors. I would also suggest adding a second box in a different location, just in case the current spot is no longer appealing to her.

I called my vet today. She wants to see her for a urine specimen to rule out an infection, which makes sense given the frequency. In the meantime, I am looking into the low-entry options you mentioned. The hesitation does seem to be about the jump, not the litter itself, as she will sometimes use the box if I lift her up and place her inside.

I will update once I have the results, but I am hopeful that a simpler box setup will solve it.
